移除 SeekBar 阴影 [英] Remove SeekBar shadow

问题描述

由于某种奇怪的原因(黑暗但不是黑色部分)，我的 SeekBar 和拇指后面有一个随机阴影.我该如何摆脱它?

I'm getting a random shadow behind my SeekBar and thumb for some strange reason (the dark but not the black part). How do I get rid of it?

我的搜索栏:

<SeekBar android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/slider"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:max="10"
    android:thumb="@drawable/thumb"
    android:progressDrawable="@drawable/progress_appearance"/>

thumb.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

<gradient
    android:startColor="#ffffffff"
    android:endColor="#ffffffff"/>

<size android:height="20dp" android:width="20dp"/>
</shape>

progress_appearance.xml(有一些我还没有删除的奇怪渐变)

progress_appearance.xml (has some weird gradient that I haven't removed yet)

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@android:id/background"
    android:paddingTop="3px"
    android:paddingBottom="3px">
    <shape>
        <corners android:radius="100dip" />
        <gradient
            android:startColor="#000"
            android:centerColor="#000"
            android:endColor="#000"
            android:centerY="0.2"
            android:angle="270"/>
    </shape>
</item>

<item android:id="@android:id/progress">
    <clip>
        <shape>
            <corners android:radius="0dip" />
            <gradient
                android:startColor="#000"
                android:centerColor="#000"
                android:endColor="#000"/>
        </shape>
    </clip>
</item>
</layer-list>

推荐答案

试试这个:

    <SeekBar android:layout_width="fill_parent"
        android:layout_height="wrap_content"
/////
        android:background="@null"
/////
        android:id="@+id/slider"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:max="10"
        android:thumb="@drawable/thumb"
        android:progressDrawable="@drawable/progress_appearance"/>
